But it seems that the 'seaweed pill' - the 'amazing tablet' than can 'fight other diseases' - doesn't actually exist in tablet form.

Willey goes on to say:

Various laboratory tests were carried out and the research team discovered that the seaweed – Leptolyngbya crosbyana – generates natural products known as honaucins with potent anti-inflammation and bacteria-controlling properties.

She then quotes one of the researchers, who points out:

"It’s a long road to go from this early-stage discovery to application in the clinic but it’s the only road if we want new and more efficacious medicines...In different arenas these compounds could be helpful, such as treating chronic inflammatory conditions for which we currently don’t have really good medicines."

Willey's article is a bit of churnalism that originated from a press release from the Scripps Institution of Oceanography at UC San Diego.

The press release said:

Scientists identified the “nuisance” organism in 2008 on the reefs directly adjacent to the National Park Pu‘uhonua o H’onaunau off the Kona coast of Hawaii. The cyanobacterium is believed to be native to Hawaii and is usually inconspicuous.

Willey 'changed' this to:

Scientists first identified the “nuisance” organism in 2008 threatening the reefs next to a national park off the Kona coast of Hawaii. The cyanobacterium is believed to be native to the islands and is usually inconspicuous.

And this bit from the original:

Choi, Gerwick and their colleagues conducted various laboratory experiments and discovered that the seaweed (the cyanobacterium Leptolyngbya crossbyana) generates natural products known as honaucins with potent anti-inflammation and bacteria-controlling properties.

Became this:

Various laboratory tests were carried out and the research team discovered that the seaweed – Leptolyngbya crosbyana – generates natural products known as honaucins with potent anti-inflammation and bacteria-controlling properties.

Incidentally, the press release does not specifically mention arthritis.
